Hard disk password
There are two hard disk passwords (HDPs):
vUser
vMaster
Note: There are two modes for the HDP: User only and Master + User. The Master + User mode requires two HDPs; the system administrator enters both in the same operation. The system administrator then provides the user HDP to the system user.
Attention: If the user HDP has been forgotten, check whether a master HDP has been set. If it has, it can be used for access to the hard disk drive. If no master HDP is available, neither Lenovo nor Lenovo authorized servicers provide any services to reset either the user or the master HDP, or to recover data from the hard disk drive. The hard disk drive can be replaced for a scheduled fee.
Supervisor password
A supervisor password (SVP) protects the system information stored in the BIOS Setup Utility. The SVP must be entered in order to get access to the BIOS Setup Utility and make changes to system configuration settings.
Attention: If the SVP has been forgotten and cannot be made available to the servicer, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee.
